One of the most compelling and frequently cited explanations is that middle managers just aren’t that into the idea, distrusting their employees to keep working without supervisors watching them like hawks. You’d hope that over time managers would get over this fear, but a new survey out of Canada suggests that trust issues persist. Microsoft Canada’s recently released Flexible Working report surveyed 1,249 employees and 642 bosses and found that while 55 percent of employees feel they’re more productive working from home, only a quarter of bosses agreed. Why were Canadian managers less than crazy about remote work? They gave Microsoft a numbers of reasons:

Just shy of half (49 percent) said the inability to talk face-to-face

The same percentage complained about lack of focus

26 percent disliked the lack of accountability

22 percent opined that that employees do less work

Still, despite the skepticism of bosses, almost half of them (42 percent) support remote working arrangements for their employees. That stat just reinforces the inevitability of remote work, according to Carolyn Buccongello, vice president of human resources at Microsoft Canada. “Boundaries between work and life are blurring. You may dismiss this as a Generation-C issue but this speaks broadly to all generations. There are pros and cons to this new way of work, but it is not going away and technology can become the key to resetting those boundaries,” she says.

She also called for bosses to rethink their distrust and focus on employees’ results, not face time. “A flexible workforce begins with leadership teams building a culture of trust and a vision that focuses on individual results rather than how much time they spend at their desk,” she says.
